I have Windows 2000 SP4 with an up-to-date, reasonably complete Cygwin environment (cygwin 1.5.5-1, gcc 3.3.1-3, etc). I use the usual "./configure, make" process. The build fails to produce executables, with output like this /bin/bash ../../libtool --mode=link cc -g -O2 -ansi -L/usr/local/lib -o ncwa.exe ncwa.o libnco.la -lnco -lintl -lm -lC -lnetcdf cc -g -O2 -ansi -o ncwa.exe ncwa.o -L/usr/local/lib ./.libs/libnco.a -L/usr/lib /usr/local/lib/libnco.a /usr/lib/libintl.dll.a /usr/lib/libiconv.dll.a -lC -lnetcdf fu000001.o(.idata$3+0xc): undefined reference to `_libc_iname' fu000002.o(.idata$3+0xc): undefined reference to `_libc_iname' fu000003.o(.idata$3+0xc): undefined reference to `_libc_iname' fu000004.o(.idata$3+0xc): undefined reference to `_libc_iname' fu000005.o(.idata$3+0xc): undefined reference to `_libc_iname' fu000006.o(.idata$3+0xc): more undefined references to `_libc_iname' follow Info: resolving _optarg by linking to __imp__optarg (auto-import) Info: resolving _optind by linking to __imp__optind (auto-import) collect2: ld returned 1 exit status When I followed exactly the same steps with exactly the same source on 14 Aug 2003 I did not encounter this error. IIRC, I had an up-to-date, reasonably complete Cygwin environment then. So I presume that the problem is caused by the installation of a newer version of some Cygwin software component in the meantime. Any suggestions on how to diagnose & solve the problem? -- Mark Hadfield "Ka puwaha te tai nei, Hoea tatou" m.hadfield@niwa.co.nz National Institute for Water and Atmospheric Research (NIWA) -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
